To all whom-t may concern:

Be it known that we, LEE RIAL and TIL- LLiM HnnnnN, citizens of the United States, residing at San Francisco, in the county of San Francisco and State of California, vhave invented new and useful Improvements in Steering-VVheel Mountings, of which the following is a specification.

Thisinvention relates to a steering wheel mounting and is a divisional application of our co-pending invention entitled Steering wheel lock, filed October 29, 1917, Serial No. 199,003.

One of the objects ofthe present invention is to provide a simple, substantial locking mechanism, whereby it becomes possible to lock or unlock the steering wheel with relation to the steering column of an automobile or other vehicle, thus making it possible Vto render the steerinflr wheel inoperative, and

furthermore, prevent unauthorized persons from appropriating or using same. Another object ofthe invention is to provide a steering wheel column of novel construction anc also to provide means operable unison with'the lock for securing the steering wheel against vertical movement on the column. Further objects will hereinafter appear.

The invention consists rof the parts and the construction Aand combination of parts as hereinafter more fully described and claimed, having reference to the accompanyingdrawings, in which Figure 1 is a plan view of an ordinary steering wheel, showing the application of the invention.

Fig. 10 is a perspective view of one of the keys employed.

Fig. 11 is a perspective view of a portion of the locking bolt.

Fig. 12 is a detail plan view of the collar, showing a split bushing interposed between the steering column and the collar.

Fig. 13 is a vertical section through the collar, showing it raised by the interposition of a plurality of washers.

Referring to the drawings in detail, A indicates the rim of an ordinary steering wheel, 2 the spokes, and 3 the hub. Formed integral with one of the spokes, as shown at 2a, is a lock housing or casing 4t, and forming a covering for said housing and a collar 5, secured upon the steering column G, is a plate 7. Slidably mounted on a bearing plate 8 secured in the bottom of the casing is a locking bolt 9, and slidably mounted on a bearing plate 10 secured `to the cover plate 7 is a releasing plate 11.

Formed as a guideway for the'bolt 9 in the bearing plate 8 is a recessed slotted section 12, andformed on each side of the locking bolt is an outwardly projecting flange 13 which is notched, as shown at 14, along the whole length of the bolt and on each side of same. Formed in the bottom bearing plate and on each side thereof are eight slots, such as shown at 15 and 16, an d formed in the upper bearing plate and also in the cover plate 7 is a similar number of alined slots 17 and 13. Adapted to be received by the alined slots 15 and 17 are eight vertically positioned key members 19, and adapted to be received by the alined slots 1G and 13 are eight key members 20. The keys are sufliciently long to project a suitable distance above the cover plate 7, as shown at 7, (see Figs. 1, 2 and G) and may, therefore, be readily manipulated when the locking mechanism is to be released or locked.

In the bottom section of the casing 4 and also in the lower bearing plate 3, in alinement with each set of slots 15 and 16, are chambers 22, and adapted to be housed by said chambers and interposed between the lower end of each key and the bottom section of the casing is a coil spring These Vin Figs. 3, l, 5 and 10. One notched side may be called the combination side while 'the opposite side may be called the free side.

The free side of each key is provided with notches, each as shown at 24, 25 and 26, while the combination side of each key is provided with two notches, such as shown at 27 and 28. The upper notches 241 and 27 are formed on the same plane and are provided for the purpose of receiving a locking spring, such as shown at 29. Theie is one locking spring for each key (sixteen in all.) and these springs are secured to each side of the releasing plate 11, and as the releasing plate normally assumes the position shown in Fig. 9, which maintains each spring in alinement with the key,.it can readily be seen that depression of any individual key against thevtension of the springs 23 will permit a spring 29 to engage one or another of the notches 24. and 2r and lock theV key against upward movement. The release of a key thus locked can only be accomplished by moving the sliding plate in the direction of arrow aby means of a knob 30 secured to the plate, as shown in Fig. 7 this movement of the sliding plate and the springs carried thereby being permitted as the cover plate is slotted, as at 31 to allow such movement. The sliding movement thus transmitted to the plate moves the springs 29 out of alineinent with each key laterally and, therefore, disengages each spring and permits the keys to return to normal raised position, due to the tension of the springs 23.

iny number oi' keys may be employed in the combination for the purpose of releasing -or locking the bolt 9. The keys thus employed for locking or releasing the bolt are turned to the position shown in Figs. 3 and 4l; that is, the combination sides of the keys are presented toward the slotted flanges 13 of the locking bolt. The keys that are not employed in the combination remain in their normal position. and present their combination sides outwardly towaid the sides of the casing, as shown in Fig. 5.

ln actual operation, supposing the keys marked a, c and Z (see Fig. 1) are employed as locking members. Then it is only necessary to depress said keys, as shown in Fig. el, .to permit the bolt to be retracted with relation to a slot 5il formed in the collar 5. This is accomplished as follows: By referring to Fig. l it will be seen that depression of the keys c and Z has lowered them to'a point where the upper notches 27 have become engaged and lockedV by the springs 29. Tt can also be seen that the lower notches 28 have assumed a position belowV the slotted flanges Y13 of the bolt which permits the bolt to travel freely.

The other position of the combination keys is shown in Fig. 3. They are here in the raised position and as such form locks for'tlie bolt, as the lowerends of the keys are in a position where they enter the slots 14 of the flanges` 13 on thelocking bolt. The bolt'cannot, therefore, be moved before the keys c and Z) in Fig. 3 have been depressed, nor can the bolt be moved .if any other keys are depressed but the fourspecified, as the depression of keys not in the combination would cause a lug 32, on the free side of the key (see Fig. 5)l to enter one of the channels formed in the flanges 13 of the bolt. Therefore itis essential that no keys but those employed in the combination, that is, keys a, b, c and cl be depressed, as it will otherwise be impossible to move the bolt. The moment the depression oiFV the combination keys has taken place it becomes possible to move the bolt by means of a knob 33 in the direction of arrow ZJ (see Fig. 7 This movement is possible as 'the flanges 13 on the bolt are in alinement with the lower notches, formed on thefree sides of the keys, that are not employed in the combination andalso because the flanges 13 are in alinement with the notches 28 formed in the combination keys as these have been depressed as described. Y Movement of the bolt for retraction is permitted the moment the kiiob is pulled in the direction oi" the arrow b, as shown. The steering wheel is in this manner released with relation to the collar and the steering column and it also becomes possible to lock the bolt in this releasedposition merely by releasing the combination keys that have been depressed; this being accomplished, as before described, by moving the knob and connected sliding plate 11 in the direction of arrow a.

The bolt, when locked in the released position, cannot be released until the combination keys are again depressed, nor can it be released or engaged with the collar until the wheel is turned to a position where the bolt is in alinement with the notch 9n formed in the collar. Tt is, therefore, essential, when desiring to lock the wheel with relation to the collar and column, to first depress the combination keys and then turn the wheel to a position where the bolt will register with the `notch 9 to permit the bolt to enter and lock, the bolt being locked and secured in the llocked position by again releasing the combination keys through a movement of the sliding plate. It is, therefore, essential to know the combination orn the lock if it is desired tolock the wheel whenthe bolt is retracted to releasing position and also if it is desired to Yrelease the wheel tounlock it with relation to the steering column. Neither operation can be performed without knowledge of the combination.

The manner of securing the collar 5 to the steering column and also the manner in which the cover plate 7 is secured to the casing are important features of the present invention. The 'collar 5 is first secured to the column 6 by means of a key 6a, then by a screw 6b, and then by the cover plate 7, the

cover plate being secured to thecasing by means of two screws 7b. These screws pass through the cover plate 7, the upper bearing plate 10,'the releasing plate ll, and the b'olt 9 and are screwed into the lower bearing vplate 8 in the bottom section of the casing, as shown at 7C. The center portion of each screw is turned down to reduce the diameter, as shown at 7d. The reduced portions thus secured extend through slots 9e, formed in the bolt, and as each slot is enlarged to the full oiameter of the screws, as shown at 9, the screws can only be removed when the bolt is moved into a positionwhere the enlarged portions r9 will line up with the screws. This position is only assumed when the bolt is midway between a complete locking or a complete releasing position. Therefore it is necessary to know the combination of the ylock so that the bolt may be released and moved to this position before it is possible to remove the screws which secure the cover plate 7 in place. It is therefore also impossible to lift the wheel or remove it from the steering column as it is first necessary to remove the cover plate and bolt before it is possible to lift the wheel oi'f of the collar.

The wheel proper is also secured against` upward movement on the collar by forming an annular vgroove therein, as shown at 5a. A lip 9d, formed on the forward end of the bolt, normally projects into this groove when the bolt is retracted and is fully projected into the slot 9 when the bolt is moved forward to locking position, the bolt beingnormally retained in the locking position by a spring 40 interposed between the rear end of the casing and the bolt, and the rearward movement of the bolt, when retracted, is limited by a stop pin 41 secured to the rear end of the casing. This pin is of considerable importance as it prevents the bolt from moving so far back that the lip 9d might move out of engagement with the annular groove 5a; also it provides a positive stop `which prevents the bolt from being moved into a position where the slots 14, formed in the iianges 13, might be out of alinement with the keys. tis necessary that an absolute alinernent should be maintained between the keys and the slots 14 on the bolt, both when the bolt is retracted and'extended, as it would otherwise be'diiicult to Vlock the bolt in either the extended or retracted position.

The sliding plate 11 may be secured to the upper bearing plate 10 in any suitable manner, but preferably as here shown by a cross bar 42 and a screw 43, the cross bar and screw permitting a sliding movement of the releasing plate, when desired, and also permitting retraction of the releasing plate to normal position by means of a spring 44. This spring is attached at one'end to the cover plate and at the opposite end to the releasing plate.

The downward movement of the vertically positioned keys which coperate with the locking bolt is, as before stated, limited by the bottom section of the casing. The upward movement is limited entirely by pins 45 extending through the keys which are adapted to engage the underside of the upper bearing plate 10. The keys, when raised, will all assume a normal plane and will also assume a normal plane if they should'all be depressed, as their movement, both in an upward and downward direction, is positively limited; the actual movement in practice being approximately one-eighth of an inch while the extreme movement of the bolt proper is one-quarter of an inch. The forward end of the bolt which enters the slotted portion of the collar is, therefore, preferably slightly tapered, to permit it to act as a wedge to tightly lock the wheel with relation to the collar and steering column and also to permit it to automatically take up the 'slight amount of wear which will naturally take place through continuous use.

The steering wheel as a whole is absolutely tamper-proof because the combination lock is so constructed that it cannot possibly be opened without knowledge of the combination and also it is impossible to wedge, clamp or otherwise lock the wheel with relation to the steering column as the post or housing 6c inclosing the lower part of the'steering column, projects up into a recess formed in the bottom of the collar, as shown at 6d. Tt can also be seen that it becomes impossible to wedge the hub of the wheel with relation to the collar as the lower end of the hub projects below the collar, while the upper end of the steering column is ,entirely coveredby the plate '7, and it is also impossible to clamp the wheel with relation to the collar or column as a cap 5@ forms a covering for the upper end of the column; and while it is turnably mounted thereon it is secured against endwise removal by the cover plate, due to the fact that its lower edge is flanged, as shown at (3f, to engage beneath the plate 7.

Every precaution has been taker. to guard against tampering or temporarily disabling the mechanism, and as it is otherwise comparatively simple and substantial in conf struction it presents no diliiculty as regards `operation to the person whois tamiliar with vthe combination. The necessity of carrying of operating the combination.

. The wheel here shown can readily be fitted to the steering column of any standard automobile even though the collar is too large or too short. If it is too large in diameter,

' it is only necessary to interpose a split bushing, such as shown in F ig. l2, and it too short, it is only necessary to interpose a few washers, such as shown in Fig. l3. lt can, therefore, be readily applied wherever desired; because no change in construction is necessary.

From the Jforegoing description it should be appreciated that means have been proy vided tor preventing the theft or use of an Y,is entirely mutilated.

automobile by any unauthorized person as it is possible to release the steering wheel from the column or post, thereby rendering it impossible to drive the car or tow it away. rEhe wheel is, furthermore, attached to the steering column in such a way that it is locked at all times which makes it difficult, if not impossible, to remove the wheel unA less the combination is known or the wheel The locking me 1hanism provided is such that the owner can change the combination at his own pleasure, but it should be understood that such a change and combination cannot be madonnless the present combination is known as the screws thathold the cover plate on the lock are so constructed that they cannot be moved while the bolt is locked in either the Ylocked or released position. The bolt must necessarily be moved to a central or neutral position halfway between the two locking bolt. As this change in combination can be 'made merely removing the cover plate, .it can be scen that comparatively little time is required and that a change may be made as often as desired. Y

Another feature thatl should be noted is the fact that the slots formed in the cover plate area little larger than the slots formed in the two bearing plates. This isfoi great importanceas all wear will betaken up by the bearing plates, thereby saving the cover plate Vand preventing a too close observer trom detectingv which keys are being used. The materials andV finish of the several parts or' the device may be such as the experience and judgment of the manufacturer may'dictate; and while we have here shown a locking mechanism applied to a steering wheel we wish it understood that it may be applied wherever a lock may be required.
